Title: Continuous prodn. of polyurethane foam blocks using flexible, widening conical distribution tube - by feeding reactive foaming mixt. beneath flattening roller and between lining sheets running on conveyor to produce block over full width of belt with no air inclusions
Inventor: STEILEN HERBERT
IPC: B29C44/46
Filed: 1995-07-14
Abstract: This method produces polyurethane block continuously. A reactive polyurethane mixture containing foaming agent, or a prefoamed froth is applied to a lower lining sheet (2) riding on a conveyor belt (1). The mixture is distributed over the width of the lining sheet and hardened. In the new method, a conically-enlarging tube (5) is used to achieve the required distribution. This tube is loaded above (8), modifying its cross section from oval to rectangular at the outlet. Also claimed is a corresp. device for continuous manufacture of polyurethane block foam.

Inventor: DOERNDORFER JOHANNES
IPC: B60K7/00
Filed: 1995-07-28
Abstract: The invention concerns a muscle-powered wheeled vehicle with an electric auxiliary drive (5) and a control unit (10) which controls the auxiliary drive to deliver an additional torque depending on the muscle force acting on the wheel (2) concerned, the muscle force being determined by a sensor (4). The drive can be integrated into the vehicle design in optimum fashion and the drive characteristics of the auxiliary drive are very easy to regulate owing to the fact that the auxiliary drive (5) is coupled in, without gears, between the wheel concerned (2) and the wheel mounting (8).

Title: Screw pipe join for weaker pipes
IPC: F16L19/08
Filed: 1995-09-21
Abstract: The pipe is held in place by a number of hardened steel clamping jaws in a design also suitable for refined steel pipework. The jaws are toothed for clamping purposes in a sawtooth design and positioned so as to positively locate the pipe but without deforming this in any way. Thus when the pipe joint is screwed tight, the pipe remains without notching etc. The screw join can be removed for re-use as required and the seal obtained can be reinforced by a compression spring  which compensates for the seal shrinkage in the longer term. The join should be stocked in cartridge etc form to prevent application errors and the join is sealed by a specially moulded seal proof against ageing or heat with a compression residue below 8%, supplemented by a polytetrafluoroethylene coating. Additional components include a surround cage , steel segments, clamping nut, a pipe made of Cu or refined steel.

Patent DE-19544973-A1 (DE)
Inventor: BORGARDT BERNHARD
IPC: B65D25/20
Filed: 1995-12-01
Abstract: The invention concerns a plastic packaging of specified shape stability and relatively large volume. The two parts (2, 3) which form the bottom part and top part respectively are essentially identical in form but of different sizes such that they have regions (6, 28, 29) which co-operate with one another to a limited degree and, when the parts are stacked together, have a positive or non-positive secure connection (7, 8, 25, 26, 27) e.g. a squeeze-grip or snap-in connection. Each of the stacked parts has a sheet thickness or strength which is not, either on its own or combined with the other part, sufficient to maintain the specified shape stability. The information medium (4), which is preferably not made of plastic and which is of a shape and substance such as to contribute to the desired shape stability of the packaging, is accommodated between the stacked parts (2, 3). Despite the immense reduction in the plastic content, the hygienic advantages of plastic packaging are retained in full. A high proportion of the total packaging is made up of paper or cardboard-type material to give stability.

Title: Belt-tension gauge for motor vehicle IC engine
Inventor: HIRANO SHIGEAKI
IPC: G01H13/00
Filed: 1996-04-25
Abstract: The meter has a vibrator (SV) which sets the belt (3) vibrating at a frequency which varies over a range which covers the belt resonant frequency. A further appliance (15) monitors the vibration amplitude and provides an appropriate output signal. A stress computing appliance (18) detects the presence of resonance from the output signal of the amplitude monitor and the frequency at which the belt is vibrating which is then used in determining the belt tension. This is derived from the expression: T = K. Ssqd. x M x fsqd. Where K = a constant S = a span length of the belt M = weight or mass of belt f = resonant vibration frequency

Title: Method of switching off torque of electric motor
Inventor: FRANK ANTON DIPL ING
IPC: H02P25/14
Filed: 1996-10-10
Abstract: The torque of the electric motor is regulated using a predefined demand revolution rate and the drive current supplied by an electrical supply device. The current is varied or regulated in steps depending on the motor revolution rate detected by a revolution rate meter. The revolution rate meter continuously monitors a motor current actual value corresp. to the revolution rate by comparison with a predefined switch-off current corresp. to the switch-off torque. Switch-off occurs when the actual value coincides with the switch-off current.
